Editorial on the Research Topic Insight into Acromegaly ComplicationsAcromegaly is a rare endocrine multisystemic disorder, caused in the vast majority of cases by a somatotroph pituitary adenoma. The excess secretion of growth hormone (GH) and consequently, of insulin like growth factor 1 (IGF1) cause many physio-pathological changes in virtually all organs and tissues (osteoarticular system, muscles, brain, heart and blood vessels, respiratory and hematopoietic system, kidneys, liver and pancreas, thyroid, adipose tissue). In addition, several important complications might appear due to adenoma compression on neighboring neural anatomic structures, upon optic pathway or oculomotor nerves from the cavernous sinuses. Compression upon the normal pituitary tissue could lead to associated pituitary insufficiency. Excess of GH and IGF-1 trigger well documented colonic and thyroid neoplastic changes. All these are considered acromegaly complications and deserve a detailed, personalized approach.Epidemiological data shows that acromegaly is diagnosed with an incidence of 3.8 cases per million, with a prevalence of 6 per 100.000 (1). However, confirmed in most studies, the long evolution until diagnosis explains the high prevalence of acromegaly complications. The highest impact upon survival is related to cardiovascular complications, while the quality of life is impacted mostly due to chronic degenerative osteoarticular changes (2).Currently, the selective transsphenoidal adenomectomy is the first line treatment, followed by medical therapy using somatostatin receptor ligands (SRLs) (3), dopamine agonists or GH receptor blocker pegvisomant. Radiotherapy is used in selected cases, especially in resistant, invasive adenomas. Presurgical treatment with SRLs could be used in selected cases, for a better hormonal and/or tumour control, especially for those with severe cardiovascular involvement and high surgical risk (4).Current Research Topic remains of high scientific and clinical interest, and includes five papers from well known pituitary research groups from Poland and Brasil.
